It might be a vitamin B12 deficiency, which can easily go months without anyone noticing
Doctors should watch for these and teach patients to recognize severe reactions
Vegans and vegetarians may require a different approach, which could include oral supplements alongside injections, based on blood test results and dietary intake
Things Worth Discussing with Your Doctor: Baseline kidney function testing (eGFR and cystatin C) before starting B12 MTHFR genetic testing if you have a family history of kidney disease Comprehensive nutrient testing (magnesium, zinc, B6, folate) Homocysteine and methylmalonic acid baseline levels Regular urinalysis every 3-6 months if youre on high doses Advanced urine tests if youre high-risk Pulse dosing schedules based on your kidney function Optimal timing for taking supplements Creating Your Personal Approach Rather than following generic guidelines, its worth developing an individualized B12 strategy based on your kidney function, genetic factors, and how your body responds to supplementation
This approach may benefit patients who want to improve metabolic efficiency rather than relying only on calorie restriction or exercise changes
